Method for Controlling the Power Supply from a Power Source to a Power Consumer

Abstract

A system and method for controlling power supply of a power source to at least one power consumer to a desired value in the range of from 0 and 100% in which the operating time of the power consumer is divided up into periods and the power output by the power source is switched on within one period only during the duty cycle which is the portion of the period length that corresponds to the desired value. Resolution provided by the present system and method is improved over known techniques for the static division of the period into equally long periods, especially in the control of light modules having low intensities. The present system and method includes the feature in which the period length is divided up into a number of blocks, every block having at least one switch segment in which the switching state can be modified, and at least one static segment in which the switching state cannot be modified.

Dependencies are inferred from the claim text.
